Infection by phloem-limited phytoplasma affects mineral nutrient homeostasis in tomato leaf tissues

Journal of Plant Physiology, 2022
Phytoplasmas are sieve-elements restricted wall-less, pleomorphic pathogenic microorganisms causing devastating damage to over 700 plant species worldwide. The invasion of sieve elements by phytoplasmas has several consequences on nutrient transport and metabolism, anyway studies about changes of the mineral-nutrient profile following phytoplasma ...

Nematode Root Herbivory in Tomato Increases Leaf Defenses and Reduces Leaf Miner Oviposition and Performance

Journal of Chemical Ecology, 2017
The outcome of plant-mediated interactions among herbivores from several feeding guilds has been studied intensively. However, our understanding on the effects of nematode root herbivory on leaf miner oviposition behavior and performance remain limited.

Influence of Sublethal Glyphosate Rates on Leaf Mineral Concentration of Tomato [PDF]

HortScience, 2000
Glyphosate at sublethal rates was applied prebloom, at-bloom, or postbloom relative to the first flower cluster to tomato (Lycopersicon esculentum Mill.) to determine the effect on foliar concentrations of N, P, K, Ca, and Mg. Glyphosate rates of 0, 1, 6, 10, 60, and 100 g·ha-1 were used to simulate the effects of spray drift.

Endophytic colonisation of tomato by the entomopathogenic fungus Beauveria bassiana: the use of different inoculation techniques and their effects on the tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae)

Journal of Plant Protection Research, 2017
Fungal entomopathogens can naturally regulate populations of various insects. The entomopathogen Beauveria bassiana (Bals.- Criv.) Vuill. is also able to endophytically colonize different plants.

Tuta absoluta-Specific DNA in Domestic and Synanthropic Vertebrate Insectivore Feces

Insects, 2023
The ecology of greenhouse pests generally involves parasitoid or predatory insects. However, we investigated whether the leaf miner Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) is part of the diet of domestic and synanthropic vertebrate ...

Prediction of annual generations of the tomato leaf miner Tuta absoluta on tomato cultivations in Egypt [PDF]

Bulletin of the National Research Centre, 2019
Abstract Background Tomato crop is the first vegetable crop in Egypt; it covers about 3% of Egypt’s total planted area. The tomato leaf miner Tuta absoluta is a polyphagous insect pest which feeds on several solanaceous plant species and preferentially on tomato causing high losses in productivity.

Early identification of Tuta absoluta in tomato plants using deep learning

Scientific African, 2020
The agricultural sector is highly challenged by plant pests and diseases. A high–yielding crop, such as tomato with high economic returns, can greatly increase the income of smallholder farmers income when its health is maintained.

Possible development of Tuta absoluta (Meyrick) on different host plants in the Republic of Srpska (Bosnia and Herzegovina) [PDF]

Agroznanje, 2016
Tomato leaf miner-Tuta absoluta Meyrick (Lepidoptera, Gelechiidae) is a serious pest of tomato. A study on possible grown host plants of T. absoluta was conducted during 2015 and 2016 in a greenhouse in the area of Banja Luka (Republic of Srpska, Bosnia ...

Plant biostimulants and their potential role in achieving the United Nations sustainable development goals

PLANTS, PEOPLE, PLANET, EarlyView.
Plant biostimulants are substances that are obtained from a variety of sources and are applied in minute quantities to enhance plant growth and vigor. In this review we detail how the use of plant biostimulants may contribute to efforts to achieving a number of the UN Sustainable Development Goals.
